Disadvantages of the ES9J4 engine
- Most problems for the owner are caused by a variety of electrical glitches.
- Even slight overheating causes leaks from numerous gaskets and seals.
- Timing belt replacement is very expensive, and driving to the last is fraught with overhaul.
- Poor-quality gasoline quickly disables candles and coils after them.
- Lambda probes can’t handle bad fuel, and replacing all four of them isn’t cheap.
